These 18 x 23" white flat Tyvek® envelopes are constructed from 14 lb. spunbonded olefin, a material that delivers significantly greater puncture, tear, and moisture resistance than standard paper envelopes. The large flat format is designed for flat or low-profile products that must arrive undamaged and unfolded.
The self-seal adhesive closure speeds outbound processing without sealing equipment, making these envelopes practical for high-volume e-commerce fulfillment, direct mail campaigns, print distribution, and architectural or engineering document shipments. The durable olefin construction holds up under rough handling, making it equally effective in warehouse pick-and-pack lines and retail back-office mailing operations.
Each envelope features a plain white exterior finish compatible with direct printing, laser labeling, and standard address labels. Cases contain 100 envelopes and ship via parcel carrier.
